42 Check that the yoke attachment s screw joint is tightened as per 6.5 Tightening. A slight gap is built into the rotor unit on delivery. These gaps will become more visible over time as wear reduces the friction. This wear process is sped up by breakout loads close to the limit value (see technical data) and/or irregular lubrication. If the gap exceeds the limit value, contact an authorised dealer or engcon Nordic AB. A rotation gap can occur either on the contact surface between the worm wheel/ worm screw or in the worm screw s axial washers. A breakout gap occurs when the contact surface between the worm wheel and wear washer are subjected to breakout loads close to the limit value, and/or by irregular maintenance. Figure 11 Figure 11 and Table 3 show maximum gap allowed before measures are necessary Table 3 42

43 The rotator element is dimensioned to withstand high breakout and rotation loads. Regular tightening of certain screw joints is necessary to ensure a long lifespan. See Table 4. Screws and thread holes must be kept very clean and the threads well lubricated. 02 Screw casing M Nm 05 Screw casing M Nm 10 Screw casing M Nm 15 Screw casing M Nm 20 Screw casing M Nm 30 Screw casing M Nm 02 Implement hitch M Nm 05 Implement hitch M Nm 10 Implement hitch M Nm 15 Implement hitch M Nm 20 Implement hitch M Nm 30 Implement hitch M Nm 05 Centre ring M Nm 10 Centre ring M Nm / 390 Nm* 15 Centre ring M Nm / 390 Nm* 20 Centre ring M Nm / 390 Nm* 30 Centre ring M Nm 02 Yoke attachment M Nm 05 Yoke attachment M Nm 10 Yoke attachment M Nm 15 Yoke attachment M Nm 20 Yoke attachment M Nm 30 Yoke attachment M Nm Table 4 * Applies for screws with a grade of
